So, I'm adding a label programatically and I'm in need of altering the top margin a little bit to the value 8. I can't do that the obvious way, so what's wrong with my thinking?
Dim LabelAdapter As New Label
LabelAdapter.text = "Adapter"
LabelAdapter.Margin.Top = 8
This gives me the error "Expression is a value and therefore cannot be the target of an assignment".
I have aspx form with several textboxes.They are populated with values from a table via retrieval of a dataview.If the row count for the dataview is 0, then I'd like to reset the values in all textboxes. How can I loop through all the textboxes and set a default value?I've tried the following, but no sucess.
For Each ctrl As Control In Page.Form.Controls
If TypeOf ctrl Is WebControls.TextBox Then
CType(ctrl, WebControls.TextBox).Text = ""
End If
Next
My first For Loop was using Page.Controls but it returned only 1 count.The textboxes are inside a tabpanel (ajax), so do I have to locate the tabpage and then find all it's controls (for each tabpage)?
I have a panel with 5 labels and 5 listviews in it. By default they are hidden. At runtime I want only the ones shown that are needed. For example, if there are enough players for three tables then three tables should show up. I know how to make the controls visible, but not sure how to control how many are actually displayed. I also think I may have to do seperate loops and seperate the control types?
Private Sub Set_Tables()
Dim tables As Long
tables = Math.Ceiling(NumPlayers / NumPerTable)

But I don't know if i posted this at the right place. I am making 40 textboxes inside a panel. And this textboxes I set it to visible=FALSE. Then I have another textbox named txtNoteam in which once the user will enter a number in this txtbox which is less than or equal to 40, those textboxes will be set to true starting from textbox1 to textbox40 depending on the number entered by the user. Example: user enters 3, then textbox 1 to textbox 3 will be set to visible.
I was successful in doing this except one thing, instead of textbox 1 to textbox 3 will be set to visible, it's the textbox 38 to textbox 40 will be set first. This means it will start from the last textbox to the first textbox instead of from textbox1 to the last textbox.
I need your help on what should I do for this to be able to set it to visible from the 1st textbox to the last textbox or is there any other ways of doing this?

I have a nested custom control that I need to set focus on. I have it all internally wired up to automatically set the focus when the form loads, but when it comes up on screen, the designated accept button for the parent form is in focus instead. Even when is disassociate the accept button it still does not set correctly. How can I ensure my desired control gets focus.
View 2 RepliesIn VB6 I would simply retrieve the user font setting from the .ini file, load into variables and then apply to the appropriate control.
text1.fontbold = userfontbold
text1.fontitalic = userfontitalic
text1.fontunderline = userfontunderline
etc.
I'm struggling to understand how to do this vb.net The following code works, but sets all three at one time
Text1.Font = New Font("Courier", 10, FontStyle.Bold Or FontStyle.Italic Or FontStyle.Underline)Since the user can have many different combinations of settings, I would like to be able to add just one of these properties at a time, but can't seem to figure out how to do it.

Also our printer doesn't print all the way to the edge, there's a white border, about the height of this little guy:If I printed from a printer that prints to the edge, will the text be in the same position as it would be if it was printed with the border around it, the text should be in the exact same position right?
1. How to get 0 padding/inner margin in the cells? I want just the border as a colored line at the next close pixel to the control in the cell. Or if border set to none, I want the controls with no gap.
2. How do I actually add/remove rows& columns? I thought this was by setting the .ColumnCount property, but if I set it to 3, and then try to access the third column, it gives exception, so it's obviously just two columns, although it also looks like 3 on the form. ? I created it in designer with 2 columns though. But I don't understand how this hangs together..

I'm using VB2008 Express. And I've been working on a "popup" to select a date range. The DateTimePicker isn't ideal because the purpose is to pick a date range, which will always be one full week, from Sunday through Saturday. The control works just fine and I'm pretty proud of it. My problem has to do with the border added when using ToolstripControlHost for this. I've included a screenshot and my code.
In the code below, assume there exists a button named "btnTimePeriod", below which I desire to show a panel, which contains a few custom items, and the panel's name is "pnlDateRangePicker".IT WORKS... but it doesn't look right. The panel itself is 147 x 326 pixels, but notice in the attached graphic that it's adding a border around the panel which I don't want. There's a border on the top, bottom, and left... but for some reason the border on the right one is especially large. Although my code doesn't expressly set it, AutoSize = true so I would have expected it to shrink around the panel.
As required, my code already does set ShowCheckMargin and ShowImageMargin false. I haven't included the code for the DrawDateCalander Sub because it's not relevant. I believe even a blank panel would yield the same result. I have no idea where this margin is coming from.
Private Sub btnTimePeriod_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTimePeriod.Click
Call DrawDateCalendar(DatePart(DateInterval.Month, FirstDisplayedSunday), DatePart(DateInterval.Year, FirstDisplayedSunday))
Call ShowControlBelow(btnTimePeriod, pnlDateRangePicker)

Today I went to the user's site for a demo. The program works fine on my HP LaserJet 1018. Data is entered into a RichTextBoxPrintCtrl and then printed on one of four labels as selected by the user at print time. For the top left (landscape) label, I set margins (50, 570, 60, 460) on the DefaultPageSettings and it correctly prints a label starting 0.5" from the left and 0.6" from the top.
On the HP OfficeJet Pro K550, the label size, left to right and top to bottom, is correct but the top mrgin is about 0.75" and the left margin is 1.0". So the label looks correct but shifted right and down so of course it does not print ont he label. I used MS Word 2003 and printed a document with 0.5" margins all the way around and it worked.I found an options in the printer's advanced properties to "minimize margins" and another to "emulate laser printer margins" but neither had any effect on my output.
It seems when I change some code while working with practice files I get green veritcal lines in the left margin of the code page I am writing. What does it mean?

In our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.

There is newer code in a follow up post. I suggest using the code in the later post rather than the code in this one. You can still read this post though. When designing a user interface, one should be conscious of how many individual controls are required to implement the functionality. In some cases an initial design may begin with many buttons or textboxes (for example) but then further review of
the actual required functionality allows for a reduction in the number of unique controls.
But other times, there isn't a better way (which will still make sense to the user of the application) then to have a series of many repeated controls. So in the cases where one can be certain that the best UI implementation for an application will require the use of multiple copies of a given control, then it often becomes necessary to maintain some method of managing all of those controls at various points
throughout the application. Doing so typically requires that one build up some collection of controls which can then be accessed by index in order to work with any given control; but this can lead to a lot of clutter in the code file which handles these control's events. For instance there will be some kind of collection declaration, some recursive routine to find all of the controls of interest, and then any number of event handler methods with long lists of Handles clauses, or additional code loops to wire up the event handling for each control.
Purpose Since most of this functionality could be considered a requirement regardless of the type of control being managed, or its required functionality, it may make sense to wrap all of the control management functionality into a single class. And since our first requirement is a collection of controls, then a base collection class could be the perfect starting point for our control manager. There are a number of existing thread around this topic, with some recent (at the time of this writing) ones being:[URL]..In this, and related, threads I have posted examples of a simple TextBoxManager and ButtonManager control. But again, with so much similar functionality required regardless of the control being managed, it would be technically possible to create a generic ControlManager(Of T As Control) class which can manage any type of control.
[Code]...
So in summary, one can facilitate managing a large number of user interface controls by building a "control manager" class which both encapsulates the list of control instances, and deals with adding and removing defined event handlers for every control it manages. The generic control manager class itself can be inherited and extended into a more specific class on a per-application basis in order to provide more application-specific functionality.

I have a maximized form that has controls at the top of it and a large DataGridView that is docked below all the controls. Its kind of like the Ribbon in MS Office. The controls cover about 1/4 of the screen at the top. I would like a way for the user to click a button to hide all the controls then automatically expand into the place the controls were so the user can view more data in the DataGridView and visa versa. For example, in MS Office Excel you can hide the ribbon by clicking a tiny button that has "^" on it.
I'm not very familiar with all the controls in Visual Studio so I would like to hear some recommendations. Is this situation ideal for a SplitContainer or ToolStripContainer or am I way off base here?
I've got a couple of these NumericUpDown controls I put on a form. Without describing too much about the form I basically want to update some variables each time one of these NumUD controls changes value. So for each NumUD I have a call to a Recalculate subroutine within their "changedValue" event.
There are actually two problems. First, if I initialize the "Value" property to something other than zero in VB2010 at DESIGN TIME it won't even open the form when I hit RUN. It gives me a "No Source Available. No symbols loaded for any call stack frame" error. The error box says "InvalidOperationException" was not handled. So if I try to set the initial value of the Value property to anything but zero of either I get this error.
